Description

Technical Field

[0001] This application belongs to the technical field of bottle cap structures, specifically relating to a wine bottle cap structure. Background Technology

[0002] In the wine packaging industry, bottle caps not only fulfill the basic function of sealing and preserving freshness, but their decorative appearance also has an increasingly significant impact on product market competitiveness. Multi-color bottle cap designs have become an important means of enhancing product recognition. Currently, most wine bottle caps adopt an integrated structural design, or undergo overall spraying and color printing after assembly. For integrated bottle caps, achieving multi-color effects requires multiple positioning spraying processes, which is not only cumbersome but also prone to blurring and color mixing at the boundaries of different color areas, reducing appearance precision. When using a post-assembly spraying method, some areas need to be masked during the spraying or printing process, increasing production time and costs, and masking areas are prone to color differences or marks, affecting the decorative effect. Furthermore, existing modular bottle caps often suffer from poorly designed inter-component connections, leading to component loosening during transportation, storage, and use. This not only damages the product's appearance integrity but may also affect the cap's sealing performance, increasing product loss rates.

[0003] As consumers' demands for product appearance continue to rise and manufacturers' needs for cost control upgrade, the limitations of traditional bottle cap manufacturing processes in terms of the difficulty of achieving multiple colors, production efficiency, and structural stability are becoming increasingly prominent. Existing technologies lack a bottle cap design that can balance convenient processing of multiple colors with structural stability, failing to meet the dual requirements of independent processing and efficient assembly of individual components in the production process, and preventing detachment during use. Therefore, a solution to these problems is urgently needed. Summary of the Invention

[0004] The purpose of this application is to provide a bottle cap structure that addresses the shortcomings of existing technologies. In practical applications, the structure, which combines components of different colors, can significantly improve the precision of the bottle cap's appearance and meet diverse design needs. At the same time, improvements to the structure prevent parts from falling off.

The fourth protrusion and the fourth recessed groove are inclined triangular structures, the fifth recessed groove is a circular groove that is recessed relative to the inside of the first connecting body, and the fifth protrusion is a circular protrusion structure or multiple consecutive corresponding partially circular protrusion structures.

[0009] As an improvement to the bottle cap structure described in this application, the upper surface of the second connector is provided with a circular sealing piece that is recessed relative to the surface. The circular sealing piece is integrally formed with a sealing boss whose bottom area is smaller than the area of ​​the circular sealing piece. The area of ​​the circular sealing piece is smaller than the opening area of ​​the second connector. The circular sealing piece and the inner ring surface of the second connector are fixedly connected by a plurality of circumferentially distributed connecting ribs. There are gaps between the connecting ribs and the gaps are connected to the passage.

[0010] As an improvement to the bottle cap structure described in this application, a sixth protrusion and a sixth recess are respectively provided on the outside of the second connecting body and inside the lower cap body.

[0013] The beneficial effects of this application are as follows: Through structural improvements, the individual components of the wine bottle cap can be independently separated, allowing each component to undergo targeted spraying to form decorative coatings of different colors. This eliminates the need for complex masking processes or multiple positioning sprayings, simplifying the processing flow for multi-color appearances. The independent spraying method ensures uniform and full color across each component, with clear and regular color area boundaries, significantly improving the decorative precision of the bottle cap and meeting diverse design needs. Simultaneously, the independent processing of individual components reduces material waste during spraying and decreases the scrap rate due to improper masking, thereby lowering overall production costs and improving production efficiency. Furthermore, the improved connection structure of the wine bottle cap in this application allows for convenient assembly of components while ensuring the tightness of the connections between them, effectively preventing the bottle cap from detaching again during subsequent transportation, storage, and use, thus ensuring the integrity of the bottle cap.

[0026] The following is in conjunction with the appendix Figures 1-7 The present application will be further described in detail with reference to specific implementation methods, but this is not intended to limit the present application.

[0027] Implementation A bottle cap structure includes: an upper cap assembly 1 and a lower cap assembly 2 matched with the upper cap assembly 1. The upper cap assembly 1 includes an upper cap body 11, a fastening cap 12 installed on the top of the upper cap body 11, a first outer ring 13 sleeved on the outside of the upper cap body 11, an upper snap-fit ​​body 14 located inside the first outer ring 13, an upper receiving space formed inside the upper cap body 11, and a first connecting body 15 located inside the upper receiving space. The lower cap assembly 2 includes a lower cap body 21, a placement groove formed on the outside of the lower cap body 21, and a placement groove located inside the placement groove. The lower receiving body 22 in the groove, the lower accommodating space formed inside the lower cover body 21, and the connecting sleeve 23 and the second connecting body 24 partially installed in the lower accommodating space are connected to the bottle mouth. The second connecting body 24 is sleeved on the connecting sleeve 23, and both the second connecting body 24 and the connecting sleeve 23 have passages that connect to the accommodating space. The second connecting body 24 has matching threaded structures on its exterior and the first connecting body 15 has matching threaded structures on its interior. The outer surfaces of the upper cover assembly 1 and the lower cover assembly 2 are both coated with decorative coatings.

[0028] In practical applications, structural improvements allow for the individual disassembly and assembly of each component of the upper cap assembly 1 and lower cap assembly 2 in this embodiment. This enables targeted spraying of each component to form decorative coatings of different colors, eliminating the need for complex masking processes or multiple positioning sprayings. This simplifies the processing flow for multi-color appearances. Furthermore, independent spraying ensures uniform and saturated colors on each component, with clear and regular color boundaries, significantly improving the decorative precision of the bottle cap and meeting diverse design requirements. Simultaneously, independent processing of individual components reduces material waste during spraying and decreases the scrap rate due to improper masking, thereby lowering overall production costs and increasing production efficiency. In addition, improvements to the connection methods between the various components of the wine bottle cap allow for convenient assembly while ensuring the tightness of the connections. This effectively prevents the bottle cap from detaching again during subsequent transportation, storage, and use, ensuring the integrity of the wine bottle cap.

[0029] In this embodiment, the upper cover body 11, the fastening cover 12 and the first outer ring body 13 are made of metal structure, so that the exposed external part of the upper cover assembly 1 is a structure with a metallic texture, which can meet the aesthetics of different groups of people and further improve its aesthetics. It is understood that the material and spray color can be selected according to actual needs without specific restrictions.

[0030] Specifically, the upper surface of the first cover 111 is provided with a downwardly recessed ring groove structure and an upper boss 114 is formed. The inside of the fastening cover 12 is provided with a fixing ring 121 surrounding the upper boss 114. The outer surfaces of the fixing ring 121 and the upper boss 114 are respectively provided with a first recessed groove 122 and a first protrusion 115 that engage with each other.

[0031] Specifically, the upper cover body 11 includes a first cover 111 and a second cover 112 connected to each other. The width of the first cover 111 is greater than that of the second cover 112 and the snap-fit ​​cover 12 is installed on the first cover 111. The first outer ring 13 is sleeved on the second cover 112. The first outer ring 13 has a partition ring 131 inside. The first outer ring 13 located above the partition ring 131 has a second recessed groove 132 and a second protrusion 113 that are mutually engaged, respectively. The first outer ring 13 located below the partition ring 131 has a third recessed groove 133 and a third protrusion 143 that are mutually engaged, respectively.

[0032] Specifically, the second cover 112 has a fourth protrusion 116 and a fifth protrusion 117 inside, and the first connector 15 has a fourth recessed groove 152 corresponding to the fourth protrusion 116 and a fifth recessed groove 153 corresponding to the fifth protrusion 117 on the outside. The fourth protrusion 116 and the fourth recessed groove 152 are inclined triangular structures, the fifth recessed groove 153 is a circular groove that is recessed relative to the inside of the first connector 15, and the fifth protrusion 117 is a circular protrusion structure or multiple consecutive corresponding partially circular protrusion structures.

[0033] Specifically, the upper surface of the second connector 24 is provided with a circular sealing piece 241 that is recessed relative to the surface. A sealing boss 242 with a bottom area smaller than the area of ​​the circular sealing piece 241 is integrally formed on the circular sealing piece 241. The area of ​​the circular sealing piece 241 is smaller than the opening area of ​​the second connector 24. The circular sealing piece 241 and the inner ring surface of the second connector 24 are fixedly connected by a number of circumferentially distributed connecting ribs 243. There are gaps between the connecting ribs 243 and the gaps are connected to the passage.

[0034] Specifically, the upper snap-fit ​​body 14 is provided with a first fixing groove 141 and a first fixing body 142 near the edge of the lower snap-fit ​​body 22. The lower snap-fit ​​body 22 is provided with a second fixing body 222 located in the first fixing groove 141 and a second fixing groove 221 for placing the first fixing body 142, respectively, near the edge of the upper snap-fit ​​body 14. The first outer ring body 13 and the lower connecting body are provided with notches 3, so that the first fixing groove 141, the first fixing body 142, the second fixing body 222 and the second fixing groove 221 are exposed relative to the outer surface of the bottle cap structure.

[0035] In practical applications, when pouring wine, the first fixing body 142 and the second fixing body 222 are first bent or cut to separate them from the corresponding second fixing groove 221 and the first fixing groove 141, so that the upper cover assembly 1 and the lower cover assembly 2 are in a rotatable state. Then, the user uses his palm or other tools to rotate and release the corresponding spiral structure in the first connecting body 15 and the second connecting body 24, exposing the top surface of the second connecting body 24, and tilting the wine to pour. The wine can flow out through the gap between the adjacent connecting ribs 243. This does not affect the normal use of the wine bottle and prevents the wine from evaporating too quickly. At the same time, the circular sealing piece 241 and the sealing protrusion 242 can effectively isolate external dust and impurities.

[0036] Specifically, a sixth protrusion 244 and a sixth recess 211 are respectively provided on the outside of the second connector 24 and inside the lower cover body 21. Both the sixth protrusion 244 and the sixth recess 211 are set as triangular structures arranged in a vertical direction. A second outer ring 25 is sleeved on the outside of the second connector 24 located on the upper part of the sixth protrusion 244. The second outer ring 25 is fixedly set between the second connector 24 and the lower cover body 21.

[0037] Specifically, a third connector 26 is installed in the lower part of the lower accommodating space. The third connector 26 is partially exposed relative to the second connector 24, and a seventh protrusion 261 is provided on the exposed part. A seventh recess 212 is provided inside the lower cover body 21 to engage with the seventh protrusion 261. An eighth protrusion 213 is provided below the seventh recess 212 to abut against the seventh protrusion 261. The second connector 24 is located between the third connector 26 and the lower cover body 21.

[0038] In this embodiment, the cooperating protrusions and recesses are used to increase the connection strength between the various components. However, protrusions and recesses of different shapes can provide better benefits. Specifically, the fourth protrusion 116 and the fourth recess 152 are inclined triangular structures, the fifth recess 153 is a circular groove recessed relative to the interior of the first connector 15, and the fifth protrusion 117 is a circular protrusion structure or multiple consecutive corresponding partially circular protrusion structures. The fourth recess 152 is formed by multiple closely arranged triangular plates. It is known that the fourth protrusion 116, the fourth recess 152, the fifth recess 153, and the fifth protrusion 117 are the threaded structures closest to the first connector 15 and the second connector 24 in the upper cover assembly 1. The first connector 15 and the upper cap body 11 are connected at the joint. The numerous and densely distributed protrusions and recesses can better disperse the force generated when the user or producer unscrews or seals the bottle cap, further protecting the integrity of the bottle cap and preventing it from falling off. Similarly, the third connector 26 is located at the joint between the second connector 24 and the lower cap body 21. Its function is to increase the connection strength between the two. The protrusions and recesses provided on the third connector 26 and the lower cap body 21 have the same function as the protrusions and recesses provided between the first connector 15 and the upper cap body 11. Furthermore, since it is located at the lower part of the bottle cap, it is provided with an eighth protrusion 213 that abuts against the seventh protrusion 261, further strengthening its connection and fixation.

[0039] Furthermore, all content not described in detail in this specification is prior art known to those skilled in the art. Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this application are within the scope of protection of this application. In addition, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
